Source: US-CERT

Systems Affected

Overview

Microsoft has released updates that address critical vulnerabilities
in Microsoft Windows and Microsoft Windows DNS Server. Exploitation of
these vulnerabilities could allow a remote, unauthenticated attacker
to execute arbitrary commands or to cause a Windows DNS server to
provide incorrect DNS responses.

I. Description

Microsoft has released updates to address vulnerabilities that affect
Microsoft Windows and Microsoft Windows DNS Server as part of the
Microsoft Security Bulletin Summary for November 2007. The most severe
vulnerabilities could allow a remote, unauthenticated attacker to
execute arbitrary commands or cause a Windows DNS server to provide
incorrect DNS responses.

Further information about the vulnerabilities addressed by these
updates is available in the Vulnerability Notes Database.

II. Impact

A remote, unauthenticated attacker could execute arbitrary commands on
a vulnerable system. An attacker may also be able to cause a Windows
DNS server to provide incorrect responses to DNS queries.

III. Solution

Microsoft has provided updates for these vulnerabilities in the
November 2007 security bulletins. The security bulletins describe any
known issues related to the updates. Administrators are encouraged to
note any known issues that are described in the bulletins and test for

distribution system such as Windows Server Update Services (WSUS).
